Being new to the hunter side of archery, my nerves have been on edge for about a week concerning letting my first broad heads fly. Besides having those razor's so close to my hand I was concerned it would be a whole new learning curve, and lots of adjustments on the bow to make them shoot like my field points. All worry is gone, I honestly think they shoot better then my field points. I took them out to 40 yards today gradually, and I am happy to say I kept all arrows less then 2" of my 1" bullseye. Denton at Rock Creek was on the money building these for me, they fly remarkably well . He said their would be little to no difference, he was right . From start to finish, Bow, sight, arrows, etc he's got me set perfectly. I don't speak the language all to well yet but these were pro hunters 5575's with slick trick 100 grain broad head s 400 spine. Confidence building.
